Well, you’re getting a Connection Refused error trying to connect to that mysql datasource at localhost:6666. Maybe its not there or not listening on that port?

I would also add that it looks like your IADemo data connection is working… and that’s going against MySQL on port 3306. I think it’s very unlikely that you’d have a separate mysql instance running on a different port… why don’t you try changing the connection string to:

```auto
jdbc:mysql://localhost:3306/Energy
```

and see if that works.
